SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 381,566, dated April 24, 1888.

Application dlcd February 15, lSEG. Serial No. 192,057. (No model.)

To @ZZ whom it may concern- Be it known that l, JAMES MARJnRrsoN, of Lawrence, county ot' Essex, and State of Massachusetts, have invented an Improvement in 5 SpinningMachincs, of which the following description, in connection with the accom panying drawings, is a specification, like letters on the drawings representing like parts.

'This invention has for its object,chietly,to provide an apparatus whereby two or more bobbins may be automatically applied to or be removed from their carrying-spindles, to thereby facilitate the operation in spinning, called doftingu7 'My invention is herein shown as applied to a spinningmachine having a series of deadspiudles surrounded by tubes attached to a builder-rail, the said tubes carrying the bobbins, the dead-spindles having eo-operating withl them yohes provided with attached whirls which surround the said tubes,the said yokes having attached to them the fliers. The foot-step rail,which supports the bearings for the lower ends of the dead-spindles, has attached to it near its ends toothed rods, which are engaged by toothed gears on a dofling shaft parallel to the said fcotstep rail,the said shaft having its bearings in boxes on a stationary orossbeam. The shaft referred to has other larger toothed gears,which engage toothed rods placed in vertical guides attached to the said bearings, and the said toothed rods at their upper ends sustain a rock-shaft having an attached arm provided with a stud, which is acted upon by a stationary cam to rock the said shaft, the said shaft having secured to it hubs, on which are adjustably attached arms that support a bar, on which is pivoted the clamps that receive the empty bobbins and apply them to the spindles. The rockshaft referred to serves as the fulcrum for other arms orlevers having pins that are acted upon by other stationary cams, the said arms or levers having at their upper ends adjustable portions,which hold the bar to which are ivoted the clamps that engage and remove the full bobbins from the spindles.

Figure l in front elevationj represents a sufficient portion ot' a spinning-machine to illustrate one practical embodiment of my invention; Fig. i, a detail showing the stepsupport; Fig. 2, a section of Fig. 1 in the dotted line 4r x. Fig. 3 is a like section in the dotted line x as', the parts being, however, in a different position, the full bobbin on the spindle having been grasped by thejaws. Fig. l is a detail showing the bobbin-receivingjaws as grasping the full bobbin and removing it from the top of the Spindle. Fig. 5 represents yet another position occupied by the clamps with relation to the spindle,one clamp having taken away the full bobbin, ,the other clamp approaching the spindle with the empty bobbin. Fig. 6 is a broken detail showing yet another position of the said parts. Figs. 7 and 8 are details chiefly to show the cams instrumental in moving the carriers for the jaws or clamps; and Fig. 9 is a partial front view of a spinningframe embodying my improvements, the frame being broken out centrally7 the spindles, fliers, tubes, bobbins, and clamps being omitted.

The framework A,ofsuitable or usual shape, to support the working parts, has a iixed crossbeam, AJ, and a fixed collar-rail, A2, which is provided with a series of holes to receive the collars a3 of the tube-bearings A3, the said tube-bearings being secured in place by suitable screws, A5, engaging the said collars.

The step rail B, as herein shown, has at,

tached to it by screws 2 a series of supportingpieces, B', (shown separately in Fig. lwhich are shaped at their lower ends, as at 3, to enter an annular groove in and thereby support the foot-steps or lower bearing, B2, for the dead spindles B3, the said supporting-pieces being so shaped and composed of spring-steel t'o thereby enable any bearing B" to be readily detached from the step-rail to permit a deadspindle to be removed from the machine.

The dead-spindles are extended upward through holes made in the cross-rail A and through the tubes a, and the upper ends of the said dead-spindles are extended above the collar rail far enough to provide for the traverse of the tube and bobbin thereon as the yarn from the flier is wound upon the bobbin in usual manner. Each tube a, connected at its lower end by suitable nuts tothe builder-rail d, receives about it asleeve, b, to which is attached not only a whirl, b', but

ICO

also a disk or plate, b2, having attached to it in suitable manner a yoke, b, the upper por tion of which is provided with a bearing to receive loosely the upper end of a dead-spindie, the upper ends of all the dead-spindles being held pressed up into the said bearings at all times, except when the full bobbins are to be doffed and empty bobbins aretobe applied, at which time and preparatory for doff ing the step-rail B will be lowered by the gear b4, fast on the doffer-shaft b5, supported in bearings bs, erected upon a plate, bi, attached to the stationary cross-rail A, the said gears, one at each end of the said shaft, engaging the toothed rods c, one at each end of the machine, the said toothed rods being connected to the said step-rail by nuts 8.

The dofIing-shaft b5 is herein shown as provided with a hand-wheel, bw, by which to turn it when the spindles are to be lowered or raised.

The yoke b3, referred to, serves as a support for and prevents vibration of the upper end of the dead-spindle. Each yoke b3 has at its upper end a suitable projection, to which is pinned or otherwise attached by a pin, 10, a iiier, d, the arms of which are bent downward nearly parallel to the sides of the yoke,and are provided with eyes 12, the legs ot' the fliers being sufficiently separated from the arms of the yoke to permit the yarn to be wound around the leg of the flier one or more times before entering the eye of the flier, the number of times the yarn is so wound about the flier-leg depending upon the amount of friction desired on the yarn and the hardness of the yarn wound upon the bobbin. The yoke or flier will be rotated in unison by bands passed about the whirls b, as usual in Hierframes.

The tubes a at their upper ends are provided with plates or washers d3, on which rest the bottoms of the bobbins d?. The builder-rail (l2 is connected to a builder-ro.d, d, provided at its lower end with a lug or` ear, 13,connected thereto by a nut, 14, the said lug being threaded to enable the connection to it of the screw 34 of the chain e, attached to the usual drum, e', of the builder-shaft e2, common to flier and cap frames, the builder-rail being moved in usual manner.

The doHing-shaft b5 has fast upon it near each end a gear, e, which is made to engage a toothed rod or rack, et, placed in a guide, e5, attached to one of the plates bi. These two toothed rods or racks at their upper ends have bearings for the reception of a rockshaft, e. This rock-shaft has fast on it arms f, provided with studs f', that enter slotsf2 of cam-plates f3, attached each by a bolt, f 4, to a bracket, f5, secured to the cross-rail A. The roclcshaft e also has fixed to it hubsg, to which the arms g are ad j ustab] y attached by the bolts g2, the upper ends of the said arms having at tached to them the bar g3, upon which is mounted opposite each dead-spindle a pair of clamps or jaws, g, normally held closed somewhat together by a spring, g5, the said clamps or jaws being adapted to have inserted in them by hand the empty bobbins d4, as shown in Figs. 3 and 5, the said bobbins being supplied to the said jaws or clamps preparatory to lifting the rock-shaft e3 and dofting the full bobbins. The rock-shaft e6 also serves as a pivot for the arms h, each arm having a pin, 15, to j ted, as shown in Fig. 2, for adjustment on the said bar, each of the said blocks having pivoted upon it by a screw or bolt, 20, the arms of a clamp or pair of jaws, h5, having broad ends 71.,made of rather thin sheet steel, concaved to embrace the full bobbins, the front ends of thel said clamps or jaws being so shaped as'to spread apart and pass about the said full bob'- bins, as in Fig. 3, when the clamps or jaws are moved from the position Fig. 2 to that shown in Fig. 3, springs 36 keeping the said jaws normally closed.

Supposing the parts to be as in Fig. 1, but with the bobbins full of yarn, then the operation of doffng will be performed, as follows: The jaws or clamps g4 will be provided with bobbins, as shown in Fig. 2, and the shaft lb5 will be turned in the direction of the arrow, Figs. 2 and 3, which will effect the depression of the step-rail, drawing the dead-spindles down into the tubes far enough to permit the full bobbins to be removed from the spindles, and this may be done whatever may be the position of the builder-rail and the tube a,- but when the builder-rail is actuated, in usual manner, to wind thekbobbins for filling, the builder-rail will usually be down when dofng takes place. As the step-rail is lowered, the rock-shaft e is correspondingly raised, and the pin 15 in the cam-slot 16 will cause the arms h h2 and the attached bar h3 and jaws or clamps hh to pass forward about the full bobbins, as in Fig. 3, and as the rock-shaft e6continues to rise from the position Fig. 3 to the position Fig. 5, the said jaws or clamps pull or lift the'full bobbins from the upper ends of the spindles, the latter descending gradually as the said clamps or jaws ascend, the jawsor clamps grasping the full bobbins a little after the spindles commence to descend. The shape iro IZO

of the cam grooves 16 is such as to cause the clamps or jaws (they having grasped the full bobbins) to retire from the spindles and' iiers to remove the said full bobbins, as in Fig.,5.

During the time that the full bobbins are being removed the jaws containing the empty bobbins will be raised with the rock-shaft e6 until the bottoms of the said empty bobbins are a little higher than the tops of the spindles, when the rock-shaft e6 will be lowered,

and at such time the pin f of'the arm f, at-

' with relation to the rising dead-spindles, so

that the said spindles as they rise enter the bobbins, and the spindles having entered the bobbins partially the jaws or clamps are pulled awaylaterally as the pins f pass into the lower straight parts ofthe cam-slots f2, leaving the empty bobbins on the spindles.

The operation may be repeated as often as desired.

When the roclrshaft e is being lifted, the studsfl travel upward in the straight or vertical parts of the slots f2; but the pin 15 is made to travel rst in a straight part of the slot 16 until it reaches the spring'switch 23, when the said stud 15 travels into the cam partolthesaid slot 1G, but when the rock-shaft descends the studsf", meeting the switches 22, are caused to travel down in the cam parts of the slotsf, but the stud 15 when it descends passes down in the straight part of the slot 16.

Fig. 5 shows the upper end ot' the dead-spia die in the position it will occupy vertically with relation to the jaws holding the full and empty bobbins when the roclrshaft ehasjust commenced to descend, and Fig.6 shows the position that the said parts will occupy as the empty bobbin is to be entered by the upper end ofthe dead spindle, the latter being moved in the direction ot' t-he arrow on it.

Viewing Fig. 4, the spindle is supposed to bc descending and thcjaws h5 to be rising, the descent of the spindles continuing until the clamps g" and h5 arrive nearly in the position Fig. 5.

Figs. 2, 3, l, 5, and (i show consecutive different positions oi` the operative parts.

I prefer to employ the independent iiiers d; but I may omit them and provide the legs of the yoke with eyes to receivethe yarn, the said yoke then serving the purpose of a hier.

My invention with but slight alteration may be used in connection with ring-spinning spindles or in twisting-machines.

In another application, Serial No. 247,930, filed August 26, 1887, I have shown means, substantially as hereinV shown, for removing full bobbins and applying empty ones to the spindles; but with the said means I have also combined other means for removing` and ap plying the caps of cap-spinning machines, and in the said application I have made claims for some of the devices herein shown when adapted for use in a cap spinning frame.

I claim 1. The spindlc-rail B, the dead-spindles,and the footsteps B2, combined with the spring holders E', upon or by which the steps are de tachably supported,substantially as described.

2.
